Location: New Orleans, LA
Objective: Leaaf was engaged by the City of New Orleans Capital Projects to provide support for the Broadmore Drainage Upgrades and Green Infrastructure Project at various public parks and playgrounds, including AL Davis Playground, Clay Square/Burke Playground, Annunciation Square, Taylor Playground, and Van McMurray Playground.
Limited Phase I Environmental Site Assessment (ESA): Leaaf conducted a limited Phase I ESA on seven sites selected for green infrastructure improvements. The objective was to identify any historic and current environmental risks associated with the redevelopment of the sites.
Phase I ESA Report: Leaaf produced reports for each site that highlighted the following recognized environmental conditions (RECs): fill material from an unknown source at each site and varying evidence of neighboring gas stations, dry cleaners, automotive junk yards, and transportation facilities.
Phase II ESA: A Phase II ESA was performed at all seven sites to further evaluate the RECs identified in the Phase I ESAs. Soil and groundwater samples were collected and analyzed for 8 Resource Conservation and Recovery Act (RCRA) metals, Polycyclic Aromatic Hydrocarbons (PAHs), Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX), hydrocarbon fractions, and dry cleaner-specific volatile organic compounds (VOCs).
Phase II ESA Report: A report detailing the results of the Phase II ESA was produced for each site. The findings were evaluated in accordance with the Louisiana Department of Environmental Quality’s (LDEQ’s) Risk Evaluation/Corrective Action Program (RECAP). Metal and PAH concentrations in fill material exceeded the RECAP screening standard at all sites except one.
